I hate the Redskins but I'll admit that Riggins was good.
However, Larry Csonka was better, IMO, because he racked up stats on a team LOADED with talent like Jim Kiick, Paul Warfield, Mercury Morris and Griese.
I was heavily into football when Riggins was playing and he was pretty much THE SHOW with the Redskins. It was amazing that teams knew they were gonna get RIGGINS, RIGGINS, (maybe) PASS and more RIGGINS and it worked. But then again, the 'Skins had likely the best O Line in the history of the game. (<grudgingly admitted, by a former Cowboys fan)
I also was able to catch some of Walt Garrison's play. He was a tough motherfucker in an age when all the NFL players were tough.
I can't comment on guys like Red Grange or Branko Nagurski. I was still swimming in Pop's balls when those guys played.
Dom Ameche looked to be a tough dude. Paul Hornung was one of the wild guys that was good, long before the league ever heard of Stabler.
Donnie Anderson was good, Moose Johnston was double-tough.
Anyone remember Steve Owens?????
